FAQs about an Irish Terrier Puppy’s Growth and Development
1. What is the average weight of an Irish Terrier puppy at 3 months?
At 3 months, an Irish Terrier puppy typically weighs between 8 to 12 pounds (3.6 to 5.4 kg). This is a critical growth phase, and proper nutrition is essential to support healthy development.
